A Russian serviceman has shot dead eight fellow soldiers and injured at least two more on a military base in the country's Far East, officials say.
The soldier – who has been detained – might have been suffering from mental health problems, they said.
The shooting happened in the village of Gorny, not far from the city of Chita, on Friday evening.
The soldier – whose name has not been released – was guarding the base at the time. He is believed to be a conscript.
The shooting happened at 18:20 local time (11:20 GMT) during a change of guard at the base in the Transbaikal region, the Russian defence ministry said.
Russian media report that two officers and six conscripts were killed.
